Note If the mobile NVR is used on a train, it is recommended that you use an additional EN50155-
compliant single-output DC-to-DC converter or let the mobile NVR tap from UPS (uninterruptible
power supply).
Note The mobile NVR accepts only 8~35 VDC for
DC input. Make sure your power source is
compliant with this voltage before you tap the
power. Supplying power over 35V will damage the
system.
